DISCHARGE OUTLET.

Application filed July 14,

Reference is had to the accompanying drawings which illustrate the preferred form of the invention; though it is to be understood that the invention is not limited to the exact details cf construction shown and described, as it is obvious that various modications thereof within the scope of the claims will occur to persons skilled in the art.

ln said drawings:

Figure 1 is a vertical sectional view of the discharge outlet of the present invention, showing the same attached to a tank; and

Fig. 2 is a side elevation of a portion of the discharge outlet, showing a modified form of attaching means for the outer cylinder thereof. 4

This invention relates to discharge outlets for tanks, and refers more particularly to dis charge outlets for car tanks which may be heated to facilitate the ydischarge of tank lading.

The primary object of this invention is to provide a discharge outlet for tanks which is characterized by its lightness in contradistinction to the relatively heavy discharge outlets now in commercial use.

A further object of the invention is the provision of a discharge outlet formed, in the main, of standard steel pipe sections connected together at one end and attached to a tank by a casting or drop forging; the resultant assembly providing a device which is easy and inexpensive to manufacture, consists of few parts, and which in operation is strong, durable and leak proof.

Another object of the invention is the provision of a discharge outlet for tanks formed primarily of standard steel pipe sections, welded at their upper ends to an attaching casting or drop forging, and connected together at their lower ends by having one of the sections shrunk onto the other.

Other objects and advantages of this invention will'be apparent from the following description takenv in conjunction with the accompanying drawings, in which A indicates a port-ion of a tank to which is secured the discharge outlet indicated generally at B.

Secured 'to the tank A by means of rivets 1 and adjacent an opening 2 formed in the 192'?. Serial No. 205,797.

comprising aring 8 having a depending annun lar flange 4, the latter having an inner annular recess 5 formed therein. The casting C is preferably internally threaded above the re-r cess 5 to secure a valve cage`6 therein. The discharge outlet includes an outer cylinder 8 and an inner cylinder9; said cylinders being preferably formed of sections of standard steel pipe or other suitable material, and the section 8 is preferably secured to the outer face of the casting C at the flange 4 thereof by welding the upper portion of the pipe section 8 to said flange at an annular recess 10 in the latter, as clearly shown at 11. The pipe section 8 is also attached to the flange 4 at the lower edge of the latter by welding the same to the flange as shown at 12, through spaced openings formed in the pipe section 8 just adjacent thelower edge of the flange 4 ofthe casting C. This last mentioned connection is merely by way of example, as obviously, openings may be formed in the upper end of the cylinder 8 above the lower edge of the flange 4, and said openings filled with weld metal 21 whereby to connect the cylinder 8 with the flange 4, as clearly shown in Fig. 2. rThe inner cylinder or pipe section 9 is the discharge pipe, and the same is arranged concentrically with respect to the pipe section 8. The upper end of the pipe 9 extends within the annular recess 5 inthe casting C and is secured to said casting at the recess by being welded thereto, as shown at 14. c

The outer cylinder or pipe section 8 is provided near its lower endwith oppositely arranged threaded openings which receive one end of inlet and outlet pipes 15 yand 16 respectively. Each of these pipes 15` and 16 c carry a nut 17 which is welded, as shown at 18, to the adjacent portion. of the cylinder 8, thus providinga `rigid connection for said pipes 15 and 16 with ythe cylinder 8.y y n The discharge nozzle of the present invention is formed by the lower ends of .pipe sections 8 and 9, and the lower end of pipe 9 is internally threaded, as shown at 19, to provide an attaching means for a discharge line, not shown, for directingmaterial discharged through the pipe 9 to a suitable storage. ,j

Cil

The inner and outer pipe sections 8 and 9 define bet-Ween them a heating chamber or space 20, and the ioWer end of the outercylinder 8 is reducedin rdiameter to lie adjacent the lower end of the inner cylinder 9.

As clearly shovvn, the outer cyiinder 8 has a portion 7 thereof turned in sharply at almost right angles tok provide a bottoni for the heating chamber; 20, the remaining lower portion of the outer cylinder vclosely engaging the lovver end of the inner cylinder 9. lt has been found desirable to connect the adjacent eX- treme ends of the inner and outer cylinders or pipe sections by Welding, as shown at 2l; such Welding being spot Welds or a complete annular Weld, as desired.

By spinning, l reduce the diameter of the levier end ofthe outer cylinder to the forni shown in the drawings, and While the outer cylinder is in a heated condition, l insert the inner cylinder 9 in position, and the lovfer or reduced end of the outer cylinder W i, cooling, shrink onto the lower end oi the inner cylinder, as will be obvious, thus efecting a close and tight fitting connection of the lower ends of cylinders 8 and 9. The upper end of the inner cylinder 9 is then Welded to rthe flange of the casting C, and pipes l5 and 16 then attached to the outer cylinder, Whereupon the entire device may be attached to the ytank by means of the rivets l.

From the above description, itis believed that the invention Will be fully apparent to those skilled in the art, but particular attention is called to the fact that l have providedk a dischargeoutlet Which is formed, in the main, of standard steel pipe sections connect- .ed to each other at their louer ends and connected to a drop forgingor casting at their upper' ends; the crop forging or casting having a depending attaching portion Which is positioned between the cylinders, the construction thus eiiecting an inner cylinder or pipe section With a surrounding jacket, and between said inner cylinder and jacket a heating space is provided through which a heating mediui'u may be circulated from the L ipe l5. V The discharge outlet of the present invention ris considerably lighter than discharge outlets heretofore known, and due kto the specific construction thereof, l have provided an outlet which is entirely leak proof thus eliminating a disadvantage which is sometimes present in the usual and now coininercially known discharge outlets fcrined of relatively expensive castings; Which castings often times are more or lessporous perniitting leakage of the heating medium therethrough and through the connections of the several parts thereof.
